1. Picking ears is a technical term, which means picking ears.

2. Visual ear-plucking means that people who pluck their ears use newly upgraded visual ear-plucking equipment. The image is clear, and a tiny hair is clearly visible. The front section is only 2.7 mm, and the visual device and ear digging tool can enter the ear canal for visual operation at the same time, so customers can watch the detailed state in their ear canal simultaneously while digging their ears.
